Can anyone help? I can send the final matrix, or the final filtered

Can you make the filtering binary large-address-aware, using some kind of linker switch in Visual Studio? Doing that and rebooting in /3gb mode will give 3GB of VM space, though that still may not be sufficient for such a big job if you only have 2GB of physical memory.

I am using VC++ 6.0 and it does not seem to recognize the 3G switch.

And the machine only has 2GB anyway......

The data arrived today but not the polynomial file. I've already sent email but if need be I can probably reverse engineer a compatible poly file. It's not that there aren't many plausible alternatives.

4*(2^129)^6+1 is the obvious one, with the reciprocal a close second.

It was the obvious one. Filtering now started, and I hope the first pass will finish overnight.

I put a file called 'polyfile' on the disk. Didn't you see it?
The poly was indeed 4x^6 + 1. (yech!)

nope, no such file on any of the disks. No matter, I've already built one ab initio and the post-processing is well underway.
